Anthurium plant named ‘ANTHAMYO’

ABSTRACT

A new  Anthurium  plant named ‘ANTHAMYO’ particularly distinguished by having wavy, shiny, strongly blistered, bright red, cordate and very durable spathes that retain the original color for a very long period of time, dark green and deltoid, durable leaves, white spadices with yellow tips, early and rich flowering continuously throughout the year, and a plant height of 33.0 cm to 38.0 cm is disclosed.

Genus and species: Anthurium andraeanum L.

Variety denomination: ‘ANTHAMYO’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium, botanically known as Anthurium andraeanum L., and hereinafter referred to by the variety name ‘ANTHAMYO’. The new Anthurium plant is a product of a planned breeding program conducted by the inventor in Bleiswijk, the Netherlands. The objective of this breeding program was to create a new 33.0 cm to 38.0 cm height plant with wavy, shiny and strongly blistered, bright red, cordate and very durable spathes.

The new variety originated from a cross-pollination made in April 2009 in Bleiswijk, The Netherlands. The female parent was a red Anthurium pot plant designated ‘8477-07’ (unpatented), and the male parent was a red Anthurium pot plant designated ‘15376-05’ (unpatented).

A single plant was selected from the progeny of the stated cross in December 2010. Asexual reproduction of the new variety by tissue culture in 2014 in Bleiswijk, The Netherlands, has demonstrated that the new variety reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations.

Plant Breeder's Rights for this variety have been applied for in the European Union on Nov. 27, 2017. ‘ANTHAMYO’ has not been made publicly available or sold anywhere in the world more than one year prior to the effective filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Bleiswijk, The Netherlands:

-   -   1) Wavy, shiny and strongly blistered, bright red, cordate         spathes;     -   2) White spadices with yellow tips; and     -   3) Green, deltoid leaves.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs which show the overall plant habit including blooms and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 34-week old plant grown in a greenhouse in Bleiswijk, The Netherlands, in November 2018. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety.

FIG. 2 shows a close-up of the mature spathe.

FIG. 3 shows a close-up of the upper leaf blade surface.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘ANTHAMYO’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 34-week old plants which were planted from tissue culture in 12 centimeter (diameter) pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in November 2018. Color readings were taken under 5000 lux natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2015).

COMPARISON WITH PARENTAL AND SIMILAR COMMERCIAL VARIETIES

‘ANTHAMYO’ differs from the female parent plant ‘8477-07’ (unpatented) in that ‘ANTHAMYO’ has medium-sized spadices, whereas ‘8477-07’ has small spadices. Additionally, ‘ANTHAMYO’ has wider spathes and taller plants than ‘8477-07’.

The male parent plant of ‘ANTHAMYO’, cultivar ‘15376-05’ (unpatented), is no longer in existence, so a meaningful comparison cannot be made.

‘ANTHAMYO’ differs from similar commercial variety ‘ANTHDUNDAL’ (U.S. Plant Pat. No. 27,287) in that ‘ANTHAMYO’ has strongly blistered spathes that are wavy in cross section, whereas ‘ANTHDUNDAL’ has slightly blistered spathes that are flat in cross section. Additionally, ‘ANTHAMYO’ has longer spathes and taller plants than ‘ANTHDUNDAL’.

‘ANTHAMYO’ differs from similar commercial variety ‘ANTHERBI’ (U.S. Plant Pat. No. 28,241) in that ‘ANTHAMYO’ has cordate, strongly blistered spathes that are wavy in cross section, whereas ‘ANTHERBI’ has orbicular-cordate, blistered spathes that are flat in cross section. Additionally, ‘ANTHAMYO’ has longer spathes than ‘ANTHERBI’. 

I claim:
 1. A new and distinct variety of Anthurium plant named ‘ANTHAMYO’, substantially as illustrated and described herein.
